CLAMP.

Application filed January 3, 1916.

To all whom it may concern:

Be it known that 1, WILLIAM H. Mc-

LAUGHLIN, a citizen of the United States,

construction and combination of parts hereinafter more particularly set forth and claimed.

In the accompanying drawings:

Figure 1 represents a perspective view of a clamp embodying my invention;

Fig. 2, a top plan view of the same not showing the rivets;

Fig. 3, a side elevation of clamp member B; and

Fig. 4 is a sectional view on the line H of Fig. 3.

A and B designate respectively the two clamp members or plates constituting the body of my improved clamp, the same having reversely bent outlines in the middle part of the clamp to provide an opening C for fitting on or around a spoke. The end parts a and b of this clamp are flat, fit snugly together and are provided with registering holes 03, through which fastening bolts D are passed, receiving thumb nuts E in the usual Way. Said opening C and the cross-section of the said spoke will be elliptical in many instances, as said opening is shown, although it may also be angular or of otherform. a

The clamp plate B is provided on the back or external face with a pair of rigid loops F, which are preferably near each other, as shown in Figs. 1, 2, 3 and 4. One of these loops is arranged on each side of the middle point of the length of said plate. The ends of an anti-skid chain may be con- Specification of Letters Patent.

veniently attached to these loops, one end to each loop, the middle part of the chain being held tightly on the tire. The same is true of any substitute anti-skid device having means of attachment to said loops.

Openings J are made in said plate behind each loop and between its ends to provide extra space for attaching the ends of the anti-skid chains.

The plate A has no loops and of course the plate B might be used with any plate permitting the attachment of the two plates securely together and providing for clamping a spoke between them. Thus, any injury to plate A will not make the loopcarrying plate B useless unless fitted to a duplicate of plate A, as would be the case if one of the loops were on plate A and the other on plate B. The two loops, projecting as they do laterally and preferably about at right angles to the longitudinal central line of the clamp between the fiat parts Z), are necessarily located when in use in the space between two spokes of the wheel and between the vertical planes of the twosides of the rim or tire, so that, when the wheel revolves, they will not strike against any adjacent parts of the vehicle, which cannot be said of clamps having parts projecting laterally beyond said planes. Also, being brought close together in the middle part of the clamp member B, my pair of loops F provide for the narrowest feasible loop of the anti-skid chain, which will consequently be bound more tightly on the tire than if the fastening ends of said chain were more widely separated.

Neither the spoke, tire, chain, nor any other part of the wheel has been shown in the drawings as they form no part of my invention; and the application of the clamp seems obvious without further illustration. I contemplate the use of the clamp with any ordinary form of wheel employing tires needing anti-skid devices.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A clamp for anti-skid devices, consisting of a pair of plates arranged opposite each other and means for holding them together, In testimony whereof, I have signed my one of said plates being provided With a name to this specification in the presence of loop presented laterally therefrom for the two subscribing Witnesses.
